Answer 2

Answer:

If the person doesn't get enough oxygen for more than 30 to 180 seconds, he/she can pass out.

Explanation:

• Anoxic brain injuries happen when the brain is completely deprived of oxygen owing to sudden cardiac arrest, choking, strangulation, and other sudden injuries.
• When the brain receives less oxygen than it requires while still receiving some oxygen, hypoxic brain damage happen.
• Only 2% of a person's body weight is made up of the brain, but it consumes 20% of the body's oxygen. The brain cannot carry out even the most fundamental tasks without it. The neurons in the brain that regulate everything from conscious processes like planning and reasoning to automatic, unconscious actions like controlling heart rate and digestion are powered by glucose.
• The brain's cells cannot digest glucose without oxygen, which prevents them from converting it into energy.
• The ultimate cause of brain death when your brain isn't getting enough oxygen is hence a lack of energy to keep brain cells alive.
